Yes, GTX is just wonderful, isn't it? Up till November last year, Castrol (dino) was the only motor oil I would allow in my engines. But times change, and people move on. I changed to Chevron Delo 400 in 11/2003. After Auto-RX clean cycle, I will use Schaeffer Supreme 7000 series 15w-40. But who knows? Depending on what I see in UOA numbers, I might just go back to Castrol again.
I had some wild and wonderful experiences with Castrol in my time. As a teenager, I raced Honda 4-stroke motorcycles with my buddies. We used Castrol GTX and Castrol HD-30, and had sadistic fun taking the tachometer needle in one side of the redline and out the other side. I recall seeing 11,500 RPM on some occasions.....did not even throw a con-rod. Those 1972-era engines are still working today, the majority have not even had their heads off for maintenance. So much for gunk and varnish build-up. And then, later, with cars, we'd sometimes forget about the oil change for 6 months at a time.....clocking up to 9,000+ miles on one fill of Castrol GTX. The oil turned really dark, but apart from that, no problems.
You are right, bud. Castrol GTX is the one, the best one.
